Was bedeutet der Fehlercode?

The engine control module (ECM) checks the circuit to the system relay coil, which is fed from a fuse in the engine bay's distribution box and is earthed in the module. The code is stored when the voltage in the circuit is too high. Possible causes are a cable shorted to ground, a damaged system relay or an internal fault in the ECM.

Mögliche Ursachen

Cable short-circuited to ground
Damaged system relay
Damaged engine control module
Internal fault in the engine control module

Was Sie tun können

1Start the engine and read the fault status; if nothing is active, the fault may have been intermittent
2Check that the relevant fuses are intact. Their locations are in the instruction manual or on the cover of the fuse box
3Use a multimeter to check that the cable to the system relay coil is not short-circuited to ground (body)
4If you have a diagnostic tool, read the fault counter and the freeze-frame values to see how often the fault has occurred
5If the fault returns, the engine control module must be replaced, which a workshop does

Symptome, die Sie bemerken können3

The engine does not start, sometimes or at all times
